GBP500M?
That's insane. With all the military camps closing, many of them ex-RAF to boot, I can't help feeling that this is a gold-plated solution to a non-problem.
Half a billion pounds? To implement basic training and professional development on an existing station that already does the same basic functions?
It would be cheaper to take say Dishforth, completely level it (say 10M) and build a spanking new camp (say another 100M).
Or completely gut Scampton and rebuild it.
Half a billion pounds? Really???
